Jeffboat

Jeffboat was a shipyard in Jeffersonville, Indiana founded by James Howard in 1834, a builder of steamboats. The company was owned by the Howard family until it was sold leading up to World War II. Following the war, it became known as the Jeffersonville Boat and Machine Company and later changed its name to Jeffboat, the more commonly used short form of its name. The company was the largest inland shipbuilder in the United States and the second-largest builder of barges before it closed in 2018.
